        <p>
      Generates a discrete random distribution function by giving a list of numerical pairs.

        <h2>Performance</h2>
        <p>
      The first number of each pair is a value, and the second is the probability of that value to be chosen by a random algorithm. Even if any number can be assigned to the probability element of each pair, it is suggested to give it a percent value, in order to make it clearer for the user.
